perfSONAR User Q&A and Other Discussion

["Garnizov, Ivan" <>]

Hello Mike,

 

There might be many reasons for MaDDash to assess the state of a connectivity as OK, despite some obvious connectivity issues.

It depends for example on the type of tests you have configured. There are also different set of thresholds and different aggregation intervals.

 

Please provide the specific test specification (tests) from your mesh. Also follow these instructions http://docs.perfsonar.net/psconfig_maddash_agent.html#determining-check-plugins-installed and provide the output of psconfig maddash-check-plugins for the specific test you are working with.

 

Please also consider some way for us to get https access to the dashboard (assuming here you have installed the perfsonar-centralmanagement bundle)

 

 

Regards,

Ivan Garnizov

Subject: [perfsonar-user] Maddash WebUI does not detect VM agent down on dashboard when VM is powered off

 

I have been running perfsonar test between 2 VMs and while the VM's are running the Maddash-webui shows the status as green.

 

When I power one of the VM or disconnect the vnic to the VM,  the status on maddash still shows the test as green. However when I click into the Panel it shows

 

Current Status: OK

Result of last check: OK

Message For Current Status: Average packet loss is 0.000%

 

But there is a break in the graph from the point when the VM was turned off.

 

When I bring the VM on and run the test again, the graph just continues to fill the area which should have been blank to show that the test was not run or a drop in datapoints.

 

Is this expected behaviour?

 

Any reason why maddash in the first case does not turn red/orange to show at least the status as Unable to find test data.

 

Thanks

 

Mike
